To all whoml it may concern.' l

Be it known that I, ARSNE PERRILLIAT, a citizen of the United States,residing at New Orleans, Orleans parish, State of Louisiana, haveinvented certain new and useful Improvements in Methods of BuildingLevees and Einbankments, the following being a full, clear, and exactdisclosure ofV the one form of my invention which I at present deempreferable. l l

For a detailed description of the present form of my invention,referencemay be had to the following specification and totheaccompanying drawings, which illustrate my invention.

My invention relates to a method of building a levee or embankment outof material excavated from an adjacent borrow-pit which is of greatwidth and shallow depth.

In brief I excavate progressively along lines transverse to the line ofthe levee or em-' bankment, operating from a series of centers alongsaidtransverse lines by means of a derrick boom type of excavator whichdigs in an arc around its point of location as a center. The materialthus excavated is delivered by the excavator to a movable transferdevice consisting of an inclined chute mounted on skids or wheels, andafter falling down this chute bv gravity the material is taken up by afollowing machine of the same general type the levee or embankment..Both machines and also the intermediate chute are move at the'same timefrom point to point along the said transverse excavating route, so thattheir normal spacing is preserved, and, after the end of one transverseroute is reached, the three devices are moved diagonally to a similarsucceeding excavating route parallel to the former one. Then the saidexcavating and transporting operation is repeated along this secondroute including the digging up of the trackway over which the machineshave traveled in making their first excursion and in proceeding thenceto the next succeeding route.

Turning to the drawings, the two excavators A and B together with theintermediate chute C are shown at the top of the ligure in their workingrelation, the tips of the booms of the two excavators being maintained ashort distance apart because of the chute to permit them to swingindependently vof each other. The chute C is about vmidway between thetwo excavators and may be conlbetween the arcs Vand deposited on Inected with the excavator B by a. cable R so as to follow that excavatorat a certain distance as the 'machines are advanced from one workingpoint to another.y The three devices being in this relation theexcavator B will -dig all the material within its working radius,excepting the trackway along which the machines move transversely to theprogress of the transverse excavation is from left to right, although itmay be from right to left if desired. Under this assumption the diggingmachine B will be first located at B1, the chute C will be located at C1close to the berm line M-M. and the transporting machine A at A1. Thenmachine B will excavate all the material of the borrowpit that is withinits radius of action-. e.

b1-excepting the trackways, such excavation being indicated in the upperpart of the figure at P, P. The material will be delivered by machine Bto the d chute and then taken up by machine A and delivered on the leveeor embankment along the are a1-a1. v When this work is completed themachines will all be moved a distance to the right or away from thelevee along the transverse excavating route. position the material willbe excavated between the arcs 512 by machine B and finally delivered onthe levee or embankment along the are a, Finally the machines will reachthe outermost position, machine B being then stationed at B2, the chuteat C2 and machine A at A2. Then the material between arcs b2 will beexcavated and delivered on the levee or embankment along the arc a2.Thereupon the machines will be moved diagonally, as indicated by thearrow lines.. to the respective positions A3, C3 and B3 and theoperation above described will be repeated, the lmaterial between arcsb3 being first excavated and delivered on the levee or embankment alongthe arc c3, the material between arcs o being delivered along the arc Inthis new ,l

.loov

0,34 and the. material between arcs b4 along the are a4.' rl`he threedevices have now reached the respective positions A4, C4, B4 and willthence be again moved diagonally to the respective positions A5, B, Cand the described operations again repeated. ln each case the .trackwaysahead of the three devices vvill be left unexcavated until after themachines have passed, when they will be included in the excavationbehind or in the rear of the machines. The chute C serves to definitelylocate the material brought in by the bucket of machine B and also tospace the machines A and B so that their booms will not interfere witheachother and the operator Will be free to work his machine without needof care to dodge the boom of the other machine. On the transversetrackways the chute rope R Will be attached to vmachine B as Shown, buton the diagonal trackways will be attached to machine A, which, as itmoves, will dravv the chute after it. The arcs of excavation will beno-n-concentric since the digging machine B works at successive stationsor excavating centers, such stations or centers being at `diiierentdistances from the levee or embankment along the tigansverse routes ortrackvvays. The succeeding transverse ioutes or trackvvays will beparallel with one another and a distance apart no greater than theradial reach of the boom so that the trackvvay behind the machine can bereached and excavated by the machine after it has passed on.

What I claim as new and desire to secure by Letters Patent is:

1. The method of building a levee or embankment which comprisesprogressively excavating an adjacent borrow-pit in a series ofsuccessive, non-concentric arcs, transporting the excavated material toand depositing it at a series of points betvveen the levee or embankmentand the points of excavation and at progressively diierent distancesfrom the said levee or` embankment, and transporting the material fromsaid pointsof deposit and delivering it onfthe levee o r embankment atprogressively diffe-rent points corresponding to changes `in location ofsaid .points of deposit.

2. The method of building a levee or embankment which comprisesprogressively excavating an adjacent borrow-pit 1n a series ofsuccessive, non-concentric arcs, transporting the excavated material toand depositing it at a series ot' points between the levee or embankmentand the points of excavation and at progressively different distancesfrom the said leveel or embankment, and transporting the depositedmaterial from said points of deposit and delivering it upon said leveeor embankment at progressively different distances from said points ofdeposit and in a series of non-concentric arcs.

3. The method of building a levee or embankment which comprisesprogressively excavating an adjacent borrow-pit n a series ofsuccessive, non-concentric arcs, depositing the material as it isexcavated and guiding the deposited material to definite locations.

which progress to nevv positions for each arc of excavation, andtransporting the material from said points of deposit and delivering iton the levee or en'ibankment at progressively different distancesconforming to the changes in location oi the points of deposit of theoriginally excavated material.

4. The method of building a levee or embankment which comprisesprogressively excavating an adjacent borrow-pit in a lseries ofsuccessive, non-concentric' arcs which succeed one another in adirection transverse to the line of the le-vee or embankment, leavingunexcavated a track-Way for the apparatus employed, transporting theexcavated material and depositing it at a series of points between thelevee or embankment and the points of excavation and at progressivelydiferent locations corresponding to the respective arcs of excavation,transporting the deposited material and delivering it on the levee orembankment in a series of non-concentric arcs at progressively diferentpoints corresponding to changes in location of the points of deposit,shifting the apparatus diagonally to a new position along the line ofvthe levee or embankment, and repeating the excavating, depositing anddelivering steps in a direction parallel to the line 'of centers of thenon-concentric excavating arcs and so as to include the previouslyunexcavated track-Way.

In Witness whereof I have hereunto set my hand, this eighth day ofOctober, 1915.
